Title: Eject lock mechanism of connector for card
Inventor: NATORI AKIRA
IPC: B42D15/10
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To compose an eject lock mechanism of a connector for a card by a small number of parts and to shorten the time required for ejection locking of the card after inserting it into the connector. SOLUTION: Figure b shows that the IC card 21 is inserted in the connector but an electromagnet 31 is not in an excited condition. In this state, an eject plate 11 is locked by a lock plate 8, and a clearance C exists between a fixed core 31A of the electromagnet and a piece 32 to be attracted attached to the eject plate. Figure c shows that insertion of the IC card into the connector is detected and the electromagnet is in excited condition. Though the eject plate is separated from the lock plate, the eject plate is locked by the electromagnet since the piece to be attracted is closely adhered to the fixed core. Since the eject plate does not move even when the lock plate rotates, the IC card is prevented from uncoupling and being ejected from the connector.
